Check Digit Verification of cas no
The CAS Registry Mumber 68048-12-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,0,4 and 8 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 68048-12:
(7*6)+(6*8)+(5*0)+(4*4)+(3*8)+(2*1)+(1*2)=134
134 % 10 = 4
So 68048-12-4 is a valid CAS Registry Number.
